Upgrades required for a Fi BL 18"?

[abaddon]

So, right now I'm running 2 12" Kicker CVX's off of a Hifonics Bxi2010d amp, and I'm pretty happy. But I want something kinda different, something bigger. I've never had bigger than 12's, and when I saw how reasonably-priced the Fi BTL and BL's were, I kinda had an idea that I wanted an 18.

A loaded BL 18 looks like it's gonna run me about 400-450 when it's all said and done. But basically just wondering what kind of possible electrical upgrades I'm going to need... Big 3 is upgraded and I'm running a second battery off of a Stinger SR80 isolator, and my voltage never drops. My alternator is a champ so far. I usually stay consistently around 13v all the time.

If I got the 18, I was probably going to buy another Hifonics Bxi2010d and run 2 to the Fi so she can be pushing more power. I was thinking of getting a dual 2 ohm so my alternator stays going good, I think 1 ohm might drain the life out of it quicker.

What do you guys think?

You can keep your amp : you have enough power to run a bl!

Do the big 3 in 0 ga. Get a dual 2 to have a 1 ohm load for your amp.

You should be good to go!
